\Vhen opening cavities in the human body during an operation, heemorrhage frequently occurs, which is difficult to staunch. More particularlyin the so-called Caesarian section, that is, the incision for openingthe pregnant uterus, through which the child isremoved, exceedinglyheavy haemorrhage occurs at the surfaces of section, which mayfrequently endanger. life. Apart from :the great injury to healthcaused'by such a great loss of blood, the quantity of blood gushing Vout makes it ditficult for the'operator tool).- tain a proper view ofthe seat of operation; This disadvantage can be removed'by repeatedlymopping the place in question, for which purpose an assistant isrequired. This will not staunch the flow of blood, however, and thisflow will continue 'uninterruptedly while stitching is proceeding. As,however, more particularly in the case of the Ceesarian section, severallayers of rowsof stitches have to be put in, the closing'of the woundwill occupy a considerable time, during which the haemorrhage willcontinue uninterrup'tedly, so that, as already stated,'there must be aconsiderable loss of blood. Forceps for clipping arteries are known, ofcourse, but cannot be used alone, more particularly in the Caesarianoperation.

The present invention has for its object to provide an appliance whichis intended to be used in such operations,more particularly theCeesarian operation, and which does not only cause the hzemorrhage tostop immediately, thus rendering. the entire seat of operation "visible,but so sets the edges of the wound with respect to one another that theoperator can make the necessary stitches without trouble and withoutundue hurry, as isnow the case.

The appliance according to the invention consists of two pairs ofclamping jaws which are adapted as regards their length and curvature tothe requirements in each case. Each of these pairs of clamping jaws areplaced, after the uterus has been opened, along one of the edges of thewound in such a manner that a sufficient portion of the edge of theWound is left projecting beyond the jaws for applying the stitches. Thetwo pairs of jaws are provided with joint parts with which they can beconnected together, so that they can be turned with respect to oneanother for drawing the edges of the wound so close together that thestitches may be applied without trouble.

In the accompanying drawings a constructional example of the inventionisillustrated. 1 Figures 1 and 4 show the pairs of clamp; ing jaws inplan view, f

Figure 2 shows the pair ofjaws of Figure 1' in side elevation; Figure3'the same pair of jaws elevation;

Figure "5 shows the pair of clamping jaws united, but opened, in planview, and

in front As will be seen from Figure 5, the appliance according to thepresent invention consists' of two pairs of clamping jaws,,jthe clampingjaws 1, 2, of whichiareof alength corresponding to the anticipatedlength of the incision. The clamping jaws may be curved in accordancewith the shape of. the organ-to be operated on, or have any other shape.In cross section, the clamping jaws, as shown in Figures 3 and 5, haveapproximately. the form of a fiat ellipse, such that there. are no sharpedges. jawsmust besufiiciently elastic, so that' the. clamping pressurecan act uniformly all over.

The clamping jawsl, 2, merge into the ex tensions 3 of the handles withsuch a curvature that each jaw has a part 4 extending beyond the handleextension, which serve the purpose, when the appliance is in use, ofgripping the blood vesselslying beyond the end of the incision, andstopping llZBIIlOIF rhage. Onthe-handle extensions 3 are the handles 5.:By this arrangement, the os pubis is, as it were, hrid'ged over'whenapplying theinstrumentduring the Ceesa'rian Figure 6 .is a frontelevation'of Figure 5.

The clamping V operation, so that the instrument can be applied eitherfrom the lower or the upper end of the incision. In each pair offorceps, the handle extensions 3 are pivoted by means of the screw 6, sothat the clamping jaws of each pair can be moved by means of theirhandles. ing jaws, after they have been applied to the edge of thewound, any suitable locking device may be provided. In theconstructional example shown in the drawings, one handle has fixed to itan arcuate bar 7 which, as indicated, is provided with notches orincisions, in which a short bar8, fixed to the other handle 5 of thesame forceps, engages by means of a tooth, not shown in the drawing, sothat the pair of clamping jaws can be locked in the required position,and held there. For connecting the two pairs of forceps togetherpivotally and releasably,

For securing each pair of clampone handle extension of each pair offorceps has fixed wit a threaded pinz'or the like 9'," on to which a.nut is screwed. Over the two pins or the like 9 of the two pairs'of' forceps, there engages a -bent membei L lia ving a slot 12, so that thepairs of forceps are so 'thatthe'view of the seat of operation is runob'scured, and, whatis moreimportannthe r otherwise'un'avoi'dable'lossof blood cannot take place. For closing the wound :by'stitching, thetwo pairs of "clamping j aws: are. app'roa'ched towards one another,whereupon the nuts 10 are tighteneddown on1the pins 9, for clamping themember 11,-when the two pairs of'cl'amping aws have been so a djustedrelatively to -one' an'o'ther'th-at' 'the edges of the wound are closetogether. The stitches are then putin' in' the usual manner almost cto'the endof the wound. "For completing the stitching, the two pairs-ofclamping. jaws are separated by releasing t'he nuts 1,0, and 1 drawingthem apart, so that they can be Withdrawn separately out of part ofQthewound not yetstitched.

Any material, for instance, steelpmay be used in the manufacture"of theappliance or,

for reducing the weight, any suitable iiight metal, as long'as it hassufficientlelastieityand strength. The means'ifor locking each positionwith respect to each.

pair of clamping jaws and-the constructional 'form"ofthe releasablepivotal connection for the two pairs of clamping jaws may of course beeflectecl in any other suitable: mannerth-an th at' shown in thedrawing.

Having now described my invention, what I elaim as new and desire tosecure by Letters Patent is I j lfAn appliance for preventinghaemorrhage during operations involving incisions in 'the walls ofcavities in-the human body, comprising in combination twopairs offorceps, each. pair of forceps comprising two pivoted members, a handleat one end of the member, a clamping jaw at the other end of the member,and a bridge member. for connecting the two, -pa-ir s'off forcepssuchlthat they can be adjusted'independentlyofwone another and rotatedwith respect to one another for drawing'the edges ofithe' incisiontogether, and canebe taken apart for'removing the vclamping jaws fromtheincision, as set forth.

2. An appliance as claimedinfclaim 1, in which the-jaws of the-membersofthe two pairs of forceps are of length corresponding tothe lengthofthe incisiomare curved in accordance with=the curvatnreof the wall ofthe cavity, and extend backwards towards the handles beyondtheflpart-offthe pivotal limbs remotest from the hinge,v as andflfor thepurposesetforth.
